During his tenure, Holder has greatly expanded the range of race-related lawsuits filed against companies, schools and governments.

For example, his department recently threatened to sue schools where African Americans are disciplined differently than Asian or white students. His agency has extracted billions of dollars in payments from banks after unintentional racial differences were detected in their lending patterns. He has also rolled back drug penalties imposed on African Americans.

Holder’s boss, President Barack Obama, recently told The New Yorker that he supported a reform of marijuana laws, partly because many Africans Americans have been jailed for violating those laws.

During the interview, Holder also threatened to sue states if his deputies see a racial purpose behind voter-identification laws that have already been approved by the Supreme Court.

Holder also hinted at a wave of new lawsuits amid the growing diversity caused by immigration.

“We have demographic changes in this nation the likes of which we have never seen before,” he said. “That could be a very divisive thing… on the other hand, if we do accept the new nation that we are about to become, that could be a very positive force.”
